This patent was a "Daniels and Woodworth planers combined", and can plane "three times as rapidly as the Daniels". A Daniels planer has a travelling bed to which the stock is shimmed and dogged to hold it firmly. The cutterhead consists of an arm that rotates horizontally above the stock, with a cutter mounted on each end of the arm. Where the Woodworth planer makes one face parallel to the opposite face, the Daniels planer makes the upper face flat and parallel to the bed.
